<Normal operation>
Next, with reference to FIG. 8, indoor air flow during normal operation of the air conditioning system 1 will be described. During normal operation, the ventilation device 20 takes in fresh outside air, and the air conditioning device 10 mixes the outside air with the air from the non-living room A and warms (or cools) it with a refrigerant. Then, the temperature-controlled air is sent to each living room through each duct 50 to keep the room temperature of each living room at a comfortable temperature and purify the air. The air in each living room passes through the undercut of the door, flows to the non-living room A, returns to the air conditioner 10, and part of the air (that is, return air) is discharged outdoors through the ventilation device 20, and the rest is warmed (or cooled) again by the air conditioner 10 and circulated to each living room. At this time, the room air conditioner 60 in each room operates according to the operation of the user who uses the room.

<rapid operation>
Since the non-living room A is not air-conditioned during normal operation, the room temperature is lower than that of the living room in winter and higher in summer. Usually, it is sufficient that only the living room is comfortable from the viewpoint of energy saving. Rapid operation can be used to

FIG. 9 shows indoor air flow during rapid operation of the air conditioning system 1 . During rapid operation, the air volume variable device 130 of the air conditioner 10 is opened, and air is supplied to the non-living room A from the supply port 131 provided in the chamber 13 of the air conditioner 10 . Since the supply port 131 is located upstream of the distribution box 14 where air is distributed to each duct 50, the total amount of air supplied to each living room via each duct 50 is larger than the total amount of air supplied to the non-living room A. The amount of air flowing through is greater.

The fresh outside air taken in by the ventilator 20 is mixed with the return air from the non-living room A by the air conditioner 10 and warmed (or cooled) by the refrigerant. A part of the temperature-controlled air is blown into each living room, and most of it is blown into the non-living room A through the supply port 131 . The air in the non-living room A is sucked from the suction port 112 and returns to the air conditioner 10, part of the return air is discharged to the outside through the ventilation device 20, and the rest is warmed (or cooled) by the air conditioner 10 again. ), and circulated to each living room and non-living room A. The supply port 131 is located at a position through which all the air supplied from the air conditioner 10 passes, and since the supply port 131 and the suction port 112 are provided in the air conditioner 10, both positions are close to each other and the air flow is restricted. Since the pressure loss is small, a large amount of air can be circulated to the non-residential room A, and rapid air conditioning (heating, cooling or dehumidification) and ventilation (air cleaning) are possible.

When the operation mode of the air conditioner 10 is other than ventilation, the room air conditioner 60 in each living room starts operating in that operation mode or operates with increased air conditioning capacity according to a command from the server 90 . An increase in air-conditioning capacity is achieved by, for example, increasing the air volume and changing the set temperature (higher value for heating, lower value for cooling). Also, when the operation mode of the air conditioner 10 is ventilation, the ventilation device 20 increases the ventilation air volume according to the command from the server 90 .

The air flow in the air conditioner 10 and the ventilator 20 during rapid operation will be described with reference to FIGS. 2, 3 and 5. FIG. In the ventilator 20, the outside air is taken in from the suction port 213, blown by the blower 211, exchanged with the air taken in from the suction port 222 while passing through the total heat exchanger 220, and is sent from the supply port 221 to the duct 51 is sent to the air conditioner 10 via.

In the air conditioner 10 , air from the ventilator 20 is sucked in through the suction port 113 by the blower 111 , and air in the non-residential room A is sucked in through the suction port 112 and cleaned by the air purification unit 115 . Then, the air from the ventilation device 20 and the air cleaned by the air cleaning unit 115 are mixed and sent to the heat exchange box 12 . In the heat exchanger box 12, a high-temperature refrigerant flows through the pipes of the heat exchanger 120 during heating to warm the air (low-temperature refrigerant flows during cooling to cool the air). The air temperature-controlled by the heat exchange box 12 is sent to the chamber 13 . In the chamber 13, since the air volume variable device 130 is open, the flow of air supplied from the supply port 131 to the non-living room A is divided into the flow of air supplied from each supply port 140 to each duct 50. .

Further, as indicated by the dashed line, part of the return air sucked from the non-living room A into the suction port 112 of the air conditioner 10 flows through the supply port 114 to the ventilation device 20 . In the ventilator 20, the air sucked from the suction port 222 exchanges total heat with the outside air while passing through the total heat exchanger 220, is blown by the blower 212, and is discharged from the discharge port 214 to the outdoors.

FIG. 10 is a flow chart showing the procedure of rapid operation processing executed by the air conditioning system 1 . When the user operates the remote control 40 to instruct the rapid operation start, the rapid operation process is started. Note that the user's instruction to start the operation quickly is also notified to the server 90 via the air conditioner 10 .

(Step S101)
The air conditioner 10 opens the air volume variable device 130 . As a result, a large amount of air is sent to the non-living room A, and air conditioning or ventilation of the non-living room A is started. After that, the processing of the air conditioning system 1 transitions to step S102.

(Step S102)
The server 90 determines whether the current operation mode of the air conditioner 10 is heating, cooling, or dehumidification. If the operation mode of the air conditioner 10 is heating, cooling, or dehumidifying (step S102; YES), the processing of the air conditioning system 1 transitions to step S103. On the other hand, if the operation mode of the air conditioner 10 is none of heating, cooling, and dehumidification (step S102; NO), that is, if the operation mode of the air conditioner 10 is ventilation, the processing of the air conditioning system 1 transitions to step S104. do.

(Step S103)
The server 90 causes the room air conditioner 60 in each living room to start operating in the same operation mode as the air conditioner 10, or increases the air conditioning capacity. Specifically, the server 90 transmits control data to the room air conditioner 60 that commands the room air conditioner 60 to operate in the same operation mode as the air conditioner 10 while it is stopped or is operating in another operation mode. In addition, the server 90 transmits control data to the room air conditioner 60 that is already operating in the same operation mode as the air conditioner 10 and instructs the room air conditioner 60 to increase the air conditioning capacity. As a result, the room air conditioner 60 starts operating in the same operation mode as the air conditioner 10, or increases the air conditioning capacity. After that, the processing of the air conditioning system 1 transitions to step S105.

(Step S104)
The server 90 increases the ventilation air volume of the ventilation device 20 . Specifically, the server 90 transmits control data to the ventilator 20 to command an increase in ventilation air volume. Thereby, the ventilator 20 increases the ventilation air volume. After that, the processing of the air conditioning system 1 transitions to step S105.

(Step S105)
The air conditioner 10 and the server 90 each determine whether or not a predetermined time T has elapsed after starting the rapid operation process. Time T is, for example, 10 minutes. If the time T has not passed since the rapid operation process was started (step S105; NO), the air conditioner 10 and the server 90 continue to execute step S105. On the other hand, when the time T has passed since the rapid operation process was started (step S105; YES), the process of the air conditioning system 1 transitions to step S106.

(Step S106)
The air conditioner 10 closes the air volume variable device 130 . As a result, the flow of air to the non-residential room A is stopped. In addition, the server 90 restores the operating state of the room air conditioner 60 or the operating state of the ventilation device 20 in each living room. After that, the air conditioning system 1 terminates the rapid operation process.

As described above, according to the air conditioning system 1 of the present embodiment, rapid air conditioning (heating, cooling, or dehumidification) and ventilation (air cleaning) of the non-living room A, which is a specific room, are possible. In addition, if the non-living room A is rapidly air-conditioned, the air volume to each living room may decrease and the temperature and humidity of each living room may not be kept comfortable. In conjunction with this, the room air conditioner 60 in each living room is controlled to operate at least in the same operation mode as the air conditioner 10, so that comfort in each living room can be maintained.

The ventilator 20 needs to be operated for 24 hours at a ventilation frequency of 0.5 times/h or more as a countermeasure against sick house syndrome, but the higher the ventilation air volume, the lower the temperature of the air entering the air conditioner 10 in winter and the higher in summer. As a result, the temperature control of the air conditioner 10 is delayed during air conditioning, making it difficult to warm (or cool) the room or increase power consumption. On the other hand, in the air conditioning system 1 of the present embodiment, the ventilation air volume is not changed in the rapid operation of the air conditioning, and the ventilation air volume is temporarily increased only in the rapid operation of the ventilation, thereby achieving both appropriate ventilation and energy saving. can be made

In addition, in the air conditioning system 1 of the present embodiment, a large amount of air sucked from the non-living room A in rapid operation passes through the air purification unit 115, so dust, viruses, bacteria, etc. in the non-living room A that have not been exhausted by ventilation can be processed quickly. In general, the non-living room A is an area that is shared by all members of the family, so rapid operation for the non-living room A has great merits not only in terms of comfort but also in terms of hygiene.

The present disclosure is not limited to the above-described embodiments, and various modifications are of course possible without departing from the gist of the present disclosure.

For example, the air conditioner 10 is provided with a communication interface for mobile communication, or uses an external communication adapter for mobile communication, without going through the router 80, for example, LPWA (Low Power Wide Area) , LTE (Long Term Evolution) or the like may be used to communicate with the server 90 . Similarly, each of the ventilator 20 and the room air conditioner 60 may also communicate with the server 90 using a communication method such as LPWA, LTE, or the like.

Also, during rapid operation, the air conditioner 10 may control the ventilator 20 and the room air conditioner 60 instead of the server 90 . Alternatively, a control device (not shown) having the same hardware configuration as the server 90 (see FIG. 7) is installed in the house H, and the control device controls the ventilation device 20 and the room air conditioner 60 during rapid operation. may be controlled, and the air conditioner 10 may be controlled.
